- “To my mutant brothers and sisters out there, I say this: No more hiding. No more suffering. You have lived in the shadows in shame and fear for far too long. Come out. Join me. Fight together in a brotherhood of our kind. A new tomorrow, that starts today.”
The Brotherhood of Mutants is/was a terrorist organization fighting for mutant supremacy over humans. They were founded and led by Magneto.
After the death of Sebastian Shaw during the Cuban Missile Crisis, Magneto forms the Brotherhood of Mutants with the remnants of Shaw's Hellfire Club. The original team consisted of Magneto, Mystique, Riptide, Azazel, and Tempest, and, soon after, they staged a raid on the CIA's headquarters to release Emma Frost from her prison and recruit her into their ranks.
